Your labmate acquires a spectrum of an aqueous solution containing the analyte with an empty reference compartment. you acquire a spectrum of the same solution using a matched quartz cuvette containing water in the reference compartment.
do you expect the maximum absorbance in your labmate’s spectrum to be greater than, equal to or less than the maximum absorbance in the spectrum which you acquired?
justify your answer using appropriate calculations. (you may assume both you and your labmate will use the same double beam uv spectrometer.)
circle one - the absorbance i measure will be (greater than, equal to or less than) the absorbance measured by my labmate.
explain and justify your answer.

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

to improve her experimental investigation, dalila should add a row in which no fertilizer is used. by a having a contrasting row in which no fertilizer is used, she will have a control group that will her understand the effects of the fertilizer in the plant developments vs the development of the plant when no fertilizer is used.
